Abstract

Disque de freinage d’un frein à disque d’un véhicule, frein à disque et essieu associés Le disque de freinage (22) comprend : - une partie cylindrique centrale (28) s’étendant sensiblement selon un axe de rotation (A-A’) et destinée à être solidaire en rotation d’un arbre rotatif (12) du véhicule ; - une partie annulaire (30) centrée sur l’axe de rotation (A-A’), s’étendant radialement par rapport à l’axe de rotation (A-A’) à l’écart de la partie cylindrique centrale (28) et destinée à entrer en contact avec un élément de freinage (24) du frein à disque (14); et - une entretoise (32) reliant la partie cylindrique centrale (28) à la partie annulaire (30) ; la partie cylindrique centrale (28), l’entretoise (32) et la partie annulaire (30) étant venues de matière, la partie cylindrique centrale (28), l’entretoise (32) et la partie annulaire (30) étant formées par de l’acier 28CDV5. Figure pour l'abrégé : Figure 1Braking disc of a disc brake of a vehicle, disc brake and associated axle The braking disc (22) comprises: - a central cylindrical part (28) extending substantially along an axis of rotation (A-A ') and intended to be integral in rotation with a rotating shaft (12) of the vehicle; - an annular part (30) centered on the axis of rotation (A-A'), extending radially relative to the axis of rotation (A-A') away from the central cylindrical part (28 ) and intended to come into contact with a braking element (24) of the disc brake (14); and - a spacer (32) connecting the central cylindrical part (28) to the annular part (30); the central cylindrical part (28), the spacer (32) and the annular part (30) being made from one piece, the central cylindrical part (28), the spacer (32) and the annular part (30) being formed by of 28CDV5 steel.
